The interaction effect in the reported current pain level on the numeric pain rating scale between pain and twitching. For participants who reported pain, their reported Current Pain Level was higher if they did not have twitching responses (5.41 ± 0.87), while it was lower if they had twitching response (0.38 ± 0.34). However, for those who did not report pain, their Current Pain Level was lower if they did not have twitching responses (0.65 ± 0.54) and higher if they had twitching responses (3.19 ± 0.56). There was a significant difference in the Current Pain Level between pain and no pain participants when they had no twitching responses, p < .001.
